Apparently the "5150" hold wasn't mandatory after all. And there have been a plethora of reports that the "Gimme More" singer was hellacious to the point that Dr. Phil (yes the bald guy with his own TV show) was brought in.

Britney reportedly tore out her IV, screamed and ranted at the hospital staff, and refused to be subdued during her short stay at the hospital. Doctors said that she has what appears to be a form of bipolar disorder, which cannot keep her at the hospital against her will.

A source reports, "Even though there is significant evidence that Brit has a bipolar disorder, Cedars cannot hold her against her will to treat such a problem. If doctors determine she is no longer a danger, they must let her go."

Back to Dr. Phil- reportedly he showed up and escorted Britney out of the facility by way of an underground tunnel. And rumor has it that there's a "Britney Spears Special" coming our way via the Dr. Phil show this coming week. The "Piece of Me" singer may even show up on the set.
